3 Claims. (01. 15-7) This invention relates to a device for cleaning lint from bobbins.

An object of the invention is the provision of a device for cleaning lint from bobbins in which a plurality of brushes revolving in planes at right angles to each other brush the ends of the bobbins while an air blast is forced through the central passage of the bobbin for cleaning the lint therefrom.

Another object of the invention is the provision of a device for cleaning lint from bobbins in which a plurality of brushes revolving at right angles to each other brush the lint from the ends of the bobbins, said bobbins being operated'by air motors, one of the air motors being provided with an exhaust port with which an end of each of the bobbins is adapted to be alined for blowing the lint from the central passage in the bobbin.

A further object of the invention is the provision of a device for cleaning lint from bobbins in which the bobbins are placed upon an endless carrier for transporting the bobbins through a horizontal path by which an end of each of the bobbins are thoroughly brushed of lint and with an air blast being forced through the central passage of the bobbin between two stages of the brushing operation.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings: 7 r

Figure 1 is a plan View of a device for cleaning bobbins constructed-in accordance with the principles of my invention,

Figure 2 is a side elevation of the same,

Figure 3 is a vertical section taken along the line 3-3 of Figure 2.

Figure 4 is a transverse vertical section taken along the line 4-4 of Figure l of the bobbin holders on an endless carrier,

Figure 5 is a view in perspective of the carrier with the bobbin in position,

Figure 6 is a fragmentary vertical section of a discharge port or nozzle for an air motor,

Figure 7 is a vertical section similar to that shown in Fig. 6 disclosing a modified form of the nozzle, and

Figure 8 is a similar view to that shown in Fig. 6 disclosing a further modified form of a nozzle.

Referring more particularly to the drawings,

l 6 designates the casing of an air motor in which is mounted a hub ll carried by an axle l2. 5 Curved vanes l3 are secured to the hub II and project in spaced relation from the hub.

The shaft I2 extends outwardly from the cas ing ill and a brush, generally designated by the numeral it, is secured to the shaft l2. The 10 brush isprovided with a hub section i5 with tufts l6 of hair projecting radially from the hub and secured in sockets within the hub.

Bearings l l are formed upon the outer or vertical faces of the casing IE! and these bearings support the shaft l2.

A casing is secured to the casing IE! to form a unitary structure. Bearings 2! are secured upon the opposite horizontal faces of the casing to support a shaft 22. A bracket 23 is secured to 20 the casings m and 20 and this bracket provides means for mounting the bobbin cleaning device in any approved manner adjacent to the moving bobbin as will be presently explained.

The casing 28 is provided with a motor similar to that illustrated in the casing ill and is adapted to be revolved by air under pressure coming through a pipe 24.

The shaft 22 extends vertically and upwardly from the casing 20 and a hub 25 of a revolving brush is secured to said shaft. Tufts 25 of hair project radially from the hub. Thus it will be seen that the brush, generally designated by the numeral 27, revolves in a plane which is at right angles to the plane in which the brush In revolves.

One end of the pipe 24 which forms a source of supply of air under pressure is rigidly connected to the casing 20 and is also supported from a tubular member 30 by means of a bracket 31.

The pipe 24 is disposed tangentially with respect to the circular casing 20 so that'th'e air motor in the casing 20 will be revolved'and this air is discharged through a pipe 32. In other words, this pipe or tubular member connects the exhaust port 33 of the casing 20 with the intake port 34 of the casing Ill.

The tubular member 30 forms the exhaust passage for the air motor in the casing l0 and is provided with a discharge port 36 and this exhaust port is adapted to be alined with an end 31 of each of the bobbins 38 as these bobbins are moved along an endless belt 39.

A modified form of the discharge nozzle shown in Figs. 2 and 6 is disclosed in Fig. 7. The tubular member 30 is substantially identical with that shown at 30. The end, however, is provided with a cone-shaped member 40 which is held in place by ribs 4|. These ribs are secured to the cone-shaped member 40 and to the inner wall of the tubular member 30 The cone-shaped member is inverted so that the wide end 42 is disposed at the discharge port 43. By this construction the air is spread in a circular manner as it leaves the port 43.

A tubular member 30 has a discharge port 45 and a web 46 secured to the inner walls of the tubular member 30 A nut 41 is formed at the central portion of the web and into which is threaded a rod 48 having a disc 49 at its outer end. This disc may be revolved for moving said disc inwardly or outwardly towards or away from the web 46 for controlling the airpassing through the discharge port 45. The endless member 39 carries a plurality of holders 59 which are formed of metal and have side walls These side walls are provided with sleeves 52 at the free ends to receive the legs 53 of a U-shaped member 54.

The inner ends of the side walls 51 are provided with sheared off portions 55 adjacent the end 31 of the bobbin 38. A lug 56 projects inwardly from the base 51 of the holder 59 and engages the end 31 of the bobbin while the bight of the U-shaped member 54 engages the opposite end.

As shown at 60 the base 51 of the holder 50 is secured to the endless member 39.

The bobbin 38 is provided with a central passage 6| and the end 31 is enlarged with a circular member 62. This circular member is provided with notches 63 which collect lint as does the central passage 6| of the bobbin.

The operation of my device is as follows: The bobbin cleaning device is connected to any fixed support by means of the bracket 23 and the air is turned on so that the conduit or pipe 24 will supply air under pressure to the motor 20. This will cause rotation of the air motor in the casing 20 and the brush 21.

The conduit or tubular member 32 provides an exhaust pipe for the air motor in the casing 20 and this air under pressure is conducted to the casing III which drives the motor in said casing. This motor is revolved and therefore revolves the brush l4.

The exhaust from the casing is conducted by the pipe 30 through the port 36 so that a blast of air is being discharged continuously from this port.

The endless member 39 is moved in any approved manner as by drums, not shown, and the bobbins 38 are supplied to the holders 50 continuously so that the ends 31 of these bobbins will be moved across the path of the brush I4 and the brush 21. The brush l4 moves through the slots Witnesses to mark:

or notches 63 located in a vertical plane and removes the lint therefrom.

As the ends 31 of the bobbins are carried along by the member 39 the ends will be brought into contact with the exhaust port 36 and a blast of 5 air will be forced through the bobbins thereby removing lint through the central passage 6| of said bobbins.

Since the belt 39 is moving continuously, the end 31 of each of the bobbins will be brought into 10 contact with the brush 21 revolving in a horizontal plane and, therefore, the notches 63 of the ends 31 of each of the bobbins will be brushed and freed of lint.

Thus it will be seen that when the bobbins are removed from the holders in the traveling carrier they will be free of lint due to the plurality of brushing operations and the blast of air from the port 36.

I claim:

1. A device for cleaning bobbins comprising an air channel, a pair of air motors at spaced points in the channel, a rotary brush operatively connected to each motor and located exteriorly of the channel, one end of the channel adapted to be connected to a source of air under pressure, the other end of the channel forming a discharge port and located between the rotary brushes, the axes of the brushes being located at an angle to each other so that the brushes will cooperate to clean the usual slotted ends of the bobbins.

2. A device for cleaning bobbins comprising a continuous air channel having enlarged circular portions at spaced points, an air motor in each enlarged portion, one end of the channel adapted to be connected to a source of air under pressure, the other end of the channel forming a discharge port and disposed between the enlarged portions,

a rotary brush adjacent each enlarged portion and operatively connected with a respective motor, the axis of one brush being disposed at an angle to the axis of the other brush, the discharge port being in a plane which cuts through the periphery of the rotary brushes.

3. A device for cleaning bobbins comprising a continuous air channel, a pair of air motors at spaced points in the channel, one end of the channel adapted to be connected to a source of air under pressure so that the motors may be driven, a rotary brush operatively connected to 0 each motor and located exteriorly of the channel, the other end of the channel being located between the brushes and in a plane which passes through the peripheries of said brushes, one brush being in a plane which is at a right angle to a plane passing through a similar section of the other brush so that the peripheries of the rotary brushes will clean portions of the ends of the bobbins which are at right angles to each other.
